I was worried in the '80s that the best abstract painting had become obsessed with materiality, and painterly gestures and materiality were up against the wall.

Quotes from the same author

I like real art. It's difficult to define 'real' but it is the best word for describing what I like to get out of art and what the best art has. It has the ability to convince you that it's present - that it's there. You could say it's authentic... but real is actually a better word, broad as it may be.

Abstraction didn't have to be limited to a kind of rectilinear geometry or even a simple curve geometry. It could have a geometry that had a narrative impact. In other words, you could tell a story with the shapes. It wouldn't be a literal story, but the shapes and the interaction of the shapes and colors would give you a narrative sense. You could have a sense of an abstract piece flowing along and being part of an action or activity. That sort of turned me on.

Abstract paintings must be as real as those created by the 16th century Italians.

Up until 35 I had a slightly skewed world view. I honestly believed everybody in the world wanted to make abstract paintings, and people only became lawyers and doctors and brokers and things because they couldn't make abstract paintings

The one thing I learned is not to say anything about my own paintings. Keep my mouth shut. You'll never stop hearing what you said. It will come back to you again and again, people will always tell you about it. Even if you were the source of what's wrong with it.
